Our Production Process
From raw material to finished product -- every step is performed in-house with precision equipment, ensuring consistent quality at every stage.
Shot Blasting / Peeling Machine
Removes surface oxidation and defects from the steel, ensuring a clean and smooth surface for further processing. This critical first step guarantees optimal adhesion for subsequent treatments.
Pointing Machine
Reduces the diameter at the ends of the bars to prepare them for the cold drawing process. Precise pointing ensures smooth entry into the drawing die, preventing material waste and die damage.
Annealing Furnace
Enhances the material structure of the steel, improving its ductility and strength, which is crucial for successful cold drawing. Controlled heat treatment cycles ensure uniform metallurgical properties throughout each bar.
Fully Automated Phosphating & Soaping Line
Applies a uniform lubricating film to the steel bars, significantly improving the cold drawing process and enhancing surface quality. Full automation ensures consistent coating thickness across every batch.
Cold Drawing Machines
The core equipment in our production process, capable of performing multiple drawing passes to achieve precise dimensions and high tensile strength. Our fleet includes combined drawing machines, inline cold drawing machines, and heavy-duty units for large-diameter, high-strength materials.
Polishing & Straightness
Our polishing machine achieves a superior surface finish (Ra 0.4-0.8) for a smooth, high-quality result, while the straightening machine ensures excellent straightness across the full bar length -- meeting the tightest flatness tolerances.
Precision Cutting Machine
Provides accurate length control and tight tolerances, ensuring that the steel bars are cut to the exact specifications required. Our CNC-controlled cutting system minimises kerf loss and delivers burr-free, square-end cuts.
Chamfering Machine
Processes the ends of the bars, creating a clean finish and precise edge for easy handling and further processing. Chamfered ends reduce the risk of injury during handling and improve fit during assembly.
Packaging Equipment
Automated bundling and labeling system for organized packaging, ensuring that our products are ready for shipment. Custom packaging options including anti-corrosion wrapping and export-grade crating are available on request.
Environmental & Auxiliary Equipment
Our wastewater and exhaust gas treatment system maintains environmental responsibility by handling industrial waste efficiently and safely. We comply with national environmental standards, ensuring sustainable and responsible manufacturing at every stage.
